Abstract: PROBLEM TO BE SOLVED: To improve the carrying throughput of a recording sheet in the case of gloss mode in both-side image formation by making the carrying speed of the recording sheet by a both-side carrying means high when the carrying speed of the recording sheet by a main body carrying means is low. SOLUTION: A recording paper P in which image formation on a first side (surface) is finished is carried to a both-side unit B by a main body paper ejection switching mechanism 22, and passes through a recording paper carrying path 21 inside a both-side unit B, so that the paper P is reversed, and joined to a recording paper carrying part being the main body carrying path which becomes the main body carrying means before a paper re-supplying part jam sensor 13 and carried and supplied again to an image forming device A. When the paper P is carried to the unit B from an image forming device A main body at a low speed, the unit B decides the carrying speed of the paper P in accordance with the carrying speed of the image forming device A main body.  After the paper P passes through the device A main body thereafter, the carrying speed of the unit B is made higher than a normal speed, so that the paper P carried inside the unit B is carried in time for the next image formation.

Filed: 1978-04-06
Abstract: PURPOSE:To reduce measurement errors and enable reflectances of arbitray curved faces to be measured by reducing optical elements such as reflecting mirrors and others and inserting apertures on the way of optical paths. CONSTITUTION:A beam 21 is relfected by a reflecting mirror 23, passes through a condensing lens 24 and is radiated to a measuring face 27. The light relfected by the measuring face 27 passes through condensing lenses 24, 26 and arrives onto a detector 29. On the other hand, a beam 22 passes through a condensing lens 25 and is radiated onto a reference face 28. The reflected light thereof passes through the condensing lens 25, is reflected by the reflecting face 23, passes through the condensing lens 26 and arrives onto the detector 29. In this way, the beams reflected by the measuring face 27 and reference face 28 are both detected and compared in the detector 29, whereby the relative reflectance is measured. With this apparatus, optical elements such as reflecting mirrors, etc. are less and therefore measurement errors are less. In addition, provision of apertures 30, 31 on the way of optical paths enables the reflected light on th back of the measuring object to be removed and therefore the measurement of the reflectances of the curved faces may be readily accomplished.
